Lawrence Oates was an Antarctic explorer who originated the famous "I may be some time," a line reported by the shortly-to-be-equally-late Capt Scott.
Titus Oates was a failed 17th century priest who fabricated a Catholic plot on the life of Charles II.
Lawrence was nicknamed Titus by his friends in the Antarctic. But even so, you'd expect the BBC to get it right.
UPDATE: Hah! They have corrected it and the story now refers to him as Lawrence "Titus" Oates. Which they distinctly did not to yesterday morning when I first read the story. Once again the media of the world bend before me like wheat in a hurricane.
